SUSPENSlON DEVICE FOR HAMMCCKS.

S-PEQIFICATION forming part of Letters Patent No. 340,239, dated April 20,1886.

Application filed February 19, 1884. Serial No. 191,217. (No model.)

To all whom, it may concern:

Be it known that I, ISAAC E. PALMER, of Middletown, in thccounty of Middlesex and State of Connecticut, have invented a new and useful Improvementin Suspension Devices for Hammocks, of which the following is a specification.

Hammocks composed of an open-worked woven or netted fabric are provided at each end with suspension-cords, which converge toward a ring or other analogous device, to which they are secured.

The object of my invention is to provide a simple and inexpensive device, with one end of which all the suspension-cords may be permanently connected, and to the other end of which may be adj ustably secured a suspensionrope, which is securely tied around a tree, post, or other hammock-support.

The invention consists in novel features in the construction of a suspension device, which are particularly hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of one end portion of a hammock and my suspension device combined therewith. Figs. 2 and 8 are respectively plan and side views of the device on a larger scale; and Figs. 4-, 5, and 6 are plans illustrating modified forms of suspension devices, all of which embody the essential features of my invention. In Figs. 2, 4, and 5 is represented the dotted outline of a rope secured to said device.

Similar letters of reference designate corresponding parts in all the figures.

A designates the end portion of a hammock, B the converging suspension-cords, O the suspensionrope, and D a tree around which the rope is securely tied, and which here serves as the hammock-support.

My improved suspension device has the several suspension-cords B permanently secured to its one end, and the end portion, 0, of the suspension-rope O is detachably and adjustably secured to its other end. This device is best shown in Figs. 2 and 3, and it may consist of a casting of malleable iron or composition.

At the lower end of this device are two eyes, a a, with which the suspension-cords B are connected; and these eyes are preferably open or divided, as at a, so that they may be bent aside to permit of the loops 1) of the suspension-cords being slipped upon them. The eyes a a may then be closed, to retain the suspension-cords upon them.

The making of the device of malleable iron or composition permits the. eyes a a to be so opened and closed.

At the upper end of the device is an eye, 0, and a neck, d, from which'the eye projects upward at an angle, as shown best in Fig. 3, and on opposite sides of the neck (I are eyes 0 e, which are depressed slightly below the level of the neck, as shown in Fig. 3. The eyes 0 c serve simply as guard-eyes to prevent the rope from being displaced when not under tension. The end portion, 0, of the suspension-rope is first passedthrough the eye a, then around the neck cl and through the eyes 6 c, and finally the free end is passed under the portion of the rope, which extends between the eyes 0 e, and between said portion and the neck d. Any pull on the rope in the direction of the arrow s-such as would be exerted by a weight in the hammoek will cause the portion of the rope to bite tightly on the portion between it and the neck (2, and the rope will thus be securely held against slip- ,ping. When the rope is relieved of strain, a

pull on the free end of the rope in the direction of the arrow 8 will tighten or take up slack in the rope, and by easing up the por tion of the rope the free end may be pushed backward and the rope lengthened. In whatever position the rope may be, a weight placed in the hammock will tighten the. portion and hold the rope securely against slipping.

The device shown in Fig. 4 has the divided eyes a a, the eyes, and the neck d, and the rope end 0 is passed through the eye and around the neck, as above described. This device differs from that before described, in not having the guard eyes e 6; but at the side of the eye a are horns or projections e, which prevent the rope from slipping forward.

The device shown in Fig. 5 has the eyes arr for the loops 2) of the suspension-cords, and the portion between the eyes forms the neck (I, z

from which the eye 0 projects. The rope passing around the neck is inserted through the eyes a a, and the latter therefore form guardeyes. The device shown in Fig. 6 has astirrup-like portion or eye, a", through which the ends of the suspension-cords may be inserted and then looped. It also has the eye 0 projecting from the neck d, and having at opposite sides horns or projections e. The suspension-rope may be applied to this device, as shown in Fig 4. 1

In the several forms of suspension device herein described the suspensioucords are all connected with one end of the device, and the suspension-rope is adjustably secured in the other end of the device by a s1ip-connection, as distinguished from a suspension-rope tied in a knot, which is difficult, if not impossible, to loosen after the hammock has been used.

In my United States Patent No. 272,311., granted February 13, 1883, I have shown a suspension device for a hammock having a T- shapcd head with which a bight in the suspension-rope is engaged; but no slip-connection is made between the suspension-rope and device, nor can the rope be shifted lengthwise in said device to raise or lower the hammock.

Vhat I claim as my invention, and desire to secure by Letters Patent, is

1. The suspension device for a hammock herein described, having at one end an eye or eyes for the attachment of the suspension-cords B and at the other end a neck, d, and an eye, 0, arranged at an angle to the neck, for the at tachment of one end portion of a suspensionrope, substantially as herein described.

2. A suspension device for a hammock, having at one end a divided eye or eyes on which looped suspension-cords may be slipped, and which may then be closed to confine the cords, and having at the other end a neck and an eye arranged at an angle to the neck, for the attachment of one end portion of a suspensionrope, substantially as herein described.

3. The suspension device for a hammock, consisting of a neck, d, an eye, 0, arranged at an angle to the neck, guardeyes e c at oppo site sides of the neck, and an eye or eyes for the attachment of suspension-cords, substantially as herein described.
